How to change the preferences so that each window displays something different? - jboss

Question

I'm trying to override values of preferences, but nothing overrides.
Does anyone know how to fix this?

public String init(#RequestParam(value = "key", required = false) String key, Model model, PortletRequest request) throws Exception {

System.out.println("KEY is : " + preferencesKey);
model.addAttribute("preferencesKey", preferencesKey);
return "index";
}
}
Output:

You need to call setValue and then store your PortletPreferences object. Note that preferences can only be stored in action phase. visit
